Cheapest protein per gram: Eggs ($0.10/g), chicken thighs ($0.04/g), canned tuna ($0.05/g) instead of breast ($0.08/g) and steak.
Bulk buys: Rice, oats, frozen chicken, peanut butter — items used 3+ times per week. Cuts ~25% off per-unit cost.
Ingredient overlap: One rotisserie chicken stretches across 3 meals. One batch of rice covers 4 dinners.
No takeout default: Skipping just 4 takeout meals/week ($15 avg) saves $60/wk = $240/mo on its own.

Frequently Asked Questions

Meal planning, macros & grocery budget questions answered

Everything you need to know about building a free meal plan, calculating your macros and cutting your grocery bill.

How do I calculate my daily calorie needs?

Use the Mifflin-St Jeor equation, which is the most accurate BMR formula for roughly 90% of people. Multiply your BMR by your activity factor (1.2 for sedentary up to 1.9 for athletes) to get your TDEE, then subtract 15–20% for fat loss or add 10% for muscle gain. The free macro calculator on this page does this automatically.

How much protein should I eat per day?

Research supports 0.7–1.2 grams of protein per pound of body weight depending on your goal. Higher end (1.0–1.2 g/lb) during fat loss to preserve muscle, moderate (0.8–1.0 g/lb) for muscle gain, and 0.7–0.8 g/lb for general maintenance and health.

How can I realistically save $500 a month on groceries?

Combine five strategies: plan meals weekly so nothing rots, buy frozen produce (nutritionally identical and ~50% cheaper), swap name brands for store brands (30–40% savings), pick the cheapest protein per gram (eggs, chicken thighs, canned tuna), and skip four takeout meals per week ($60/week on its own).

Is the meal plan and macro calculator really free?

Yes. The macro calculator, 7-day meal plan, grocery list, meal prep playbook, 30-day transformation program and all 12 nutrition modules are 100% free. No account, subscription or paywall.

How many meals per day should I eat?

Meal frequency is personal preference as long as you hit your daily calorie and protein targets. Most people do well with 3 meals plus 1–2 snacks. Intermittent fasting (16:8) works for some. Athletes and high-calorie goals often prefer 4–5 meals for digestion and consistent energy.

What is the best diet for sustainable weight loss?

The best diet is the one you can sustain. Research consistently shows a 15–20% calorie deficit, adequate protein (0.8–1.0 g per pound of body weight), plenty of fiber (25–35 g/day) and foods you actually enjoy outperforms any specific named diet over the long term.

How much water should I drink per day?

A practical target is about 35 ml per kg of body weight (roughly half an ounce per pound), plus an extra 500 ml on training days. Spread intake across the day and front-load it; don't chug a liter with meals as it can dilute digestive enzymes.

Can I follow this meal plan on a budget under $100/week?

Yes. The included grocery list totals $94.92 for one adult eating 5 meals/day at 2,100+ kcal and 160 g protein. A family of four can stay under $150/week using the same ingredient-overlap principles.
